How proximity steals energy from nanoresonators

Nanomechanical resonators are miniature vibrating structures on chips that oscillate at frequencies ranging from a few kilohertz to gigahertz. They are used as ultrasensitive detectors of mass and force, temperature and pressure, ...

Scientists observe water's behavior in a single molecular layer

New research has revealed that water behaves differently when confined to spaces just one molecule thick. For the first time, scientists have directly measured the vibrational signatures of truly two-dimensional water. In ...

Engineers discover 'unexpected motion' in drug-delivery robots

One day, tiny swimming robots may travel through the human body to deliver drugs. The medication would target only areas of need—chemotherapy drugs for a tumor, for example—avoiding healthy tissue and minimizing side effects. ...

Molecular nanostructures can be activated using ultrasound

Researchers from Heinrich Heine University Düsseldorf (HHU) have taken an important step toward developing intelligent molecular materials. The team headed by Dr. Bernd M. Schmidt (Institute of Organic Chemistry and Macromolecular ...
